Yakovlev showed that any Eberlein compactum is hereditarily -metacompact. We show that this property actually
characterizes Eberlein compacta among compact spaces of finite
metrizability number. Uniformly Eberlein compacta and Corson
compacta of finite metrizability number can be characterized in an
analogous way.
